MECHANICAL MOVEMENT.

To all whom z't may concern.

Be vit known that I, AUGUST J. Mo'r'rLAU,

, afcitizen of the United States, residing in @the gay and` county of Philadelphia, in the llataftef'-of` Pennsylvania, have invented cer- "1"t'aiirinew. and useful Improvements in V- ".Mecha'nical Movements, of which the folu. flowing is a true and exact description, ref-l erence being had to the accompanying draw'-` ings,'which form a part thereof.

The primary object of my present invention is to provide simple and effective means for transmitting movement from one part to another, which will permit the' amplitudeof the relative movements of the two partsl to be readily varied.

While not absolutely limited to. such v use, my invention is primarily devised for use in converting a periodic movement lof one'part into a periodic movementof vary..`

ing amplitude ofanother part; and by the term periodic movement I mean to include to and' "frofgmovements in straight and 'curved'paths and also circular movement.

`a crafnkpin into an oscillatory or recipro- -The variousfeatures of' novelty charac-v terizing my invention are pointed out with particularity inv thev claims annexed to Aand v forming. a. part of 'this specification.

'The invention is especially adapted for A'usevin 'converting the circular movement of catory 4'movementof varying amplitude.

l' fa better understanding' of the invention,

however, and of the advantages possessed l 'by it, reference should be' had to the accom elevation on the lin`e`3'-3 of Fig. 1;,Fig. 4f I is a section 'on'fthe line 4-4 ofFig. v3; Fig. 5 is a lanview of aportion ofv 'thefapparatus s ownin'Figs. 1jaf`n`d2, Fig. 6 is a somewhat diagrammatic -re resentation.- of a slightly modifiedformo the apparatus shown in Figs. 17and'2and Figs. 7 8 .and

A connecting rod B, journaled at .itsupperl end on the crank pin A2, `is pivotally connectedvat Yits lower endby a pivot pinB to one end of eachof two-links @fand E. 'The effective lengths of the links C and'E, that v1s, the 'distance 'between' .the centersof the pivotalconnections lat the opposite 'endsof 4the link, kis the same in each case. 'The opposite end ofthe link C is pivotally lconnected by the pivot -pin` D :to a lever D. The lever TD is pivvota'll'y` connected to thefr'amework X by the'lfulcrum pin D2. yThe end of vthe, link E remote from thepivot pin B is con# nected by the pivot pin E to the arm F of a rock shaft F. The latter is normally stationary, but may be angularly adjusted".

, The means shown for angularly adjust- 'ing the shaft F comprises arms F2 secured to the Vshaft F and provided with slideways F 3 receiving slideblocks Gz'in which are journalcd' the trunnion extensionsl G of a nut G working, on the screw spindle H. The latter is journaled at its lower end in the framework X, as by means of the ball and cent its upper end, the shaft H isjournaled in the framework portion X which forms a housing for the gearing by which the shaft H may be rotated in either direction from the shaft A. This mechanism comprises a gear wheel I loosely mounted on the shaft H and having gear teeth I in mesh with the Worm A4 on the shaft A, and having bevel gear teeth I2 in mesh with a bevel gear idler J, the supporting shaft J of which` extends transversely to the shaftH and also to the shaft A and is journaled in `the housing X. The gear J also meshes with the teethl 2 of the bevel gear a', also loosely mounted on*v the shaft H.

The gears I and z' are formed in their adjacent ends with conical friction surfaces` I3 and i3,,respectively, adaptedI to be operatively connected by the corresponding'end ofa friction clutch member K, splined on the shaft H and axially movable thereon by means of a rock shaft L having arms L permits of the manual rotation of the shaft shaft A in one direction or the other, ac"

cording to which of the gears I or i is engaged by the member K. A hand wheel H2,

secured to the upper end of the shaft H,

H, regardless of whether or not the shaft A is in rotation.

A lever d is mounted," and is connected to the crank pin A3,. as the lever D is mounted, and isconnected'to the pin A2. lIt will be understood, of course, the levers D and d 'with their operating connections are duplicates; and that this duplication is not essential, for each operates entirely independentV of the other.

. The manner in which the circular movement ofA the crank pin AZ is caused to impart oscillatory movementv 'of varying am- -plitude to the lever D will be readily understood from Figs; 6 to 9 inclusive, which show the positions occupied in diierent adjustments of a mechanism essentially the rsame as that-shown in Figs. 1 to 5, exceptV that in Figs. 6 to 9- the shaft H is arranged to operate on the shaft F through arms f2' at the opposite side of the shaft F and arm F and 1n Figs. 6 to 9 the only means shown for rotating the shaft H is the hand wheel H2.-

By referring to Fig. 6,' it willA be seen that the pathof the movement of the axis of the pivotal connection E', as the shaft F is angularly adjusted is an arc M, intersecting 'the arc of movement N of the'axis 'of the pin Dabout the horizontal 'connection D,

at the point lm.. With the axis of the pivotal connection E on the convex side of the arc- .N, as shown in Figs. 6 and 7 'the circular movement of the crank pin A2 willcause the pivotal'c nnection B to move along a corresponding arc 0,;and this will cause the pivotal connection D to move back and forth along the arc N. The amplitude of angular movement of the pivotal connection D and of lever D increases with the distance' of the .axis of the pivotal connection v E from the arcvN, as is obvious from a comparison of Figs. 6 and 7. `When adjusted to the condition shown in Fig. 8, in which I the axis of the pivotal connection E inter' sects the arc M, the oscillatory movement of theV ivotal connection Eproduced by the" cran pin A2 andconnecting rod B, will not Y produce any movement at all of the -pivotal connection E or of the -lever D. "When the ypivotalconnection E is carried to the inner or concave slde of the arc N, as shown in Fig. 9, the amplitude of movementV of vthe lever again corresponds to the distance of the axis of the pivotal connection E from the arc N, but the motion of the lever D isv m reversed or shifted 180 degrees in hase, so

to speak, from that which it was originally z'. e., the movement of theconnecting rod B movements imparted to the lever d by*the shaftA will differ in phaseonly from those imparted to the lever D a's the shaft F isA angularly adjusted.

It will be apparent to-those skilledv in vthe art that the mechanism disclosed is capable of use for many widely different purposes,

and that changes may be made in the forms.:

of mechanism disclosed without departing from the spirity of the invention claimed' herein.

Having now described my invention, what -I claim as new and desire to secure by Letters Patent, is:
